Sub Process Drill down?

[Elk]

Hi there...

I am currently evaluating Enterprise Arcchitect and I was wondering if it was possible to have a link from one process to another.

e.g.  If you have an Activity Diagram and one of the activities is "Prepare Mail Shot"  I want to be able to click on that activity and it will take me to another activity diagram showing the actvities needed to prepare a mail shot.

e.g. Address Evenelopes ---> Assemble Letters ---> Frank Envelopes.

Any help with this would really be apprecated.
